3.3. General Recommendations For Hydraulic Connections
W A R N I N G !
The units may produce hot water at temperatures as high as 194°F (90°C). All hydronic
components must be selected for this temperature.
When setting up the hydraulic circuit for the gas cooler, it is good practice to comply with the
following prescriptions and with the national and local regulations
.
It is recommended to connect
the piping to the heat pumps using flexible joints in order to prevent transmission of the
vibrations and compensate for thermal expansion
.
Install the following components on the piping:
•
Stop cocks, temperature and pressure indicators for maintenance and unit inspection
.
•
Sample points on the input and output pipes to read the temperature, if temperature
indicators are not present
.
•
Shut-off valves to isolate the unit from the hydraulic circuit
.
•
Metal mesh filter with openings not wider than 1/16" (1 mm) on the exchanger inlet pipe
to protect the ex- changer against slag or impurities in the pipes
.
•
Air vents installed at the highest parts of the hydraulic circuit in order to allow excess air
to be released
.
•
Expansion tank and automatic charging valve for maintenance of the system pressure
and to compensate for thermal expansion
.
•
Drain valve and where necessary, drain tank to empty the system for maintenance
operations or seasonal breaks
.
I M P O R T A N T
It is highly recommended to install a safety relief valve on the hydraulic circuit. If serious
anomalies should arise in the system (e.g. a fire breaks out), this allows the system to be
drained to prevent an explosion. Always connect the drain to a pipe with a diameter no less
than that of the valve opening and direct it towards the areas where the discharge cannot
harm anyone.
